Questione giuridica chiave
Whether the federal appeal had become moot after the building project was withdrawn.
Decisione estratta
The appeal had become devoid of purpose and the case was struck from the docket; the challenged permit and cantonal judgment were likewise moot.
Motivazione estratta
Withdrawal of the permit request eliminated the subject matter of the dispute, so the Federal Court removed the case from the register and dealt only with costs.
